AXEL S. VOGT, OF ALTOONA, PENNSYLVANIA.

AUTOMATIC OIL-FEEDING DEVICE.

Application filed April 14, 1914.

To all whom it may concern:

Be it known that I, AXEL S. Voe'r, a sub ject of the King of Sweden, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Oil- Feeding Devices, of which the following is a specification.

This invention relates to power oil feeding devices of the positive force feed or plunger-pump type adapted to be used in connection with steam engines, steam locomotives, automobiles or other similar machines, wherein it is desirable that the moving parts be thoroughly lubricated auto matically with a constant unfailing supply of oil.

The primary object of this device is to deliver a constant supply of oil to the parts to be lubricated, and to effect this through a simple positive mechanism that is itself thoroughly lubricated by the oil that is afterward forced through the device which is positioned in piped relation with the mechanism that it is designed to lubricate.

Another object of this device is to provide means whereby the oil can readily be forced through the various parts and pipe lines to the mechanism to be lubricated before the total mechanism is in normal operation, thus providing very efl ectively against the possible operation of delicate machinery without suflicient lubrication during the initial movements of the machine.

A further object of the device is to provide means for straining the oil prior to its introduction and passage to the oil plungers, thus insuring against injury to the delicate mechanism or the clogging of valves by foreign substance in the oil.

A still further object of this improved device is to provide a force feed oil pump that will deliver a number of constant streams of oil simultaneously with the oil plunger movements with a minimum number of valves.

VViththe above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

Specification of Letters Patent.

Patented June 1, 1915.

Serial No. 831,762.

It will be readily understood by those skilled in the art that this invention is quite susceptible to a wide range of structural modi cations without departing from the spirit or scope of the invention, but a preferred and thoroughly practical embodiment of the same is shown in the accompanying drawings in which Figure 1 shows a vertical sectional view of this improved force feed lubricator. Fig. 2 shows an end elevation of the parts shown in Fig. 1, and for the sake of clearness, is shown partly in section. Fig. 3 is a sectional view taken on the line 33 of Fig. 2 and fully illustrates the arrangement of oil plungers and the manner of connecting the oil plungers to the driving yokes. Fig. 4; is a partial section taken on the line 44 of Fig. 1. Fig. 5 embodies side and edge views of one of the oil plunger driving yoke arms which are shown in Figs. 1 and 2 of the drawings. Figs. 6, 7, and 8 are side, sectional and top plan views respectively of the oscillating yokes shown in operative position in Figs. 1 and 2 of the drawings. Fig. 9 is a sectional view taken on the line 1313 of Fig. 4 and shows the valve arrangement for controlling the direction of the oil flow.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

In carrying out this invention there is provided an oil reservoir designated in its entirety by the numeral 10 having attached thereto an oil filling cap 11, which is provided with a lid or cover device 12 adapted to be held in its open or closed position by a spring 13. Positioned between the filling cap 11 and the body 10 of the reservoir, I provide an extension neck portion 14: which is held in position on the body by means of a plurality of bolts 15. The bottom face 16 of the neck portion 14 1 provide with a finished recessed surface 17 which alines with and fits over the finished interlocking shoulder 18 on the body 10 of the reservoir. This construction insures perfect alinement of parts and at the same time facilitates the assembling of the oil screens 19 and 20, arranged one within the other and positioned within the said neck I l. The mesh of the inner screen 20 is preferably coarser than the mesh in the outer screen 19, thus providing in a very practical way for the perfect cleansing of the oil before it reaches the oil reservoir 10. It is also desirable to point out in this connection the advantages secured in providing the screen 20 as shown in Fig. 1 0f the drawings. The screen 20 as will be observed is arranged in alinement with the filling orifice 21, and is held in position by the spring plate 22, which is attached to the cap 11 by a suitable rivet 23, which passes through the web 24 of the'cap. The web 24 being in direct alinement with thefilling orifice 21, readily acts as a guard against injury to the screen 20. The screen 19 is also likewise protected against injury.

-Transversely across the top of the reservoir 10 is preferably arranged a shaft 25, journaled in bearing caps 26, and carrying a plurality of swinging yokes 27 journaled thereon as at 28, for actuating oil plungers 29. Approximately midway between the bearing shaft 25 and the oil plungers 29, there is located an operating shaft 30, which carries eccentrics 31 and 32, adapted to give an oscillatory motion to the swinging yokes 27 upon rotationof the shaft 30. For the purpose of rotating the shaft 30, I have provided two separate means; viz, a power actuated lever 33 and a hand operated lever 34 having a handle 35. In order to prevent backward rotation of the eccentric shaft 30 through the medium of the hand operating lever, I have provided a roller ratchet device 36, which consists essentially of a disk 37, positioned within a casing 38, and having a plurality of clutch rollers 39 adapted to wedge between the inside surface 40 of the casing 38 and the disk 37 upon the backward rotation ofthe crank 34 in the manner common to the conventional type of rollerclutch.

With further reference to the construction shown in Fig. 9 it will be observed the easing designated as 38 is located at the opposite side of the device, as clearly shown in Fig.1. A disk 37 and a roller 39 cooperate with the wedge faces of the disk and face 40 of the casing 38 to lock the opposite end of the shaft 30 against backward rotation as previously stated. Further in connection with the swinging yokes 27 it will be observed that the method of lubricating the shaft bearings 28 and the eccentrics 31 and 32 amply provides for sufficient lubrication of these'parts long after the oil level has fallen below the bottom of the eccentrics.

That is to say, there is provided in the top of each of the yokes 27 a fiber-containing cavity C from which the oil passes through the opening 28 to the shaft bearings 28. After lubricating the shaft 25 the surplus oil flows down through oil leads'28 to lubricate the points of contact between the eccentrics 31 and 32 and the yoke arms. assured that the bearings are thoroughly lubricated regardless, of the height of the oil level in the reservoir 10. Each of the swinging yokes 27 includes a pair of yoke arms 41 which are clamped to the body 13 of the yoke by means of suitable bolts 42. The lower portion of'each voke arm is offset from the main portion thereof so that when the two arms are clamped in place on each side of the body B their lower ends meet. For the purpose of holding the ends of the oil plungers within the lower portion of the yoke arms each of the'latter is provided with a transverse groove 43 one edge 44 of which is curved andlower than the other, and is provided with a notch 45 which intersects the groove. Thus, when the two arms Thus, it is 41 areclamped on the yoke body B and their lower ends are held together by the bolts 46 the transverse grooves 43 and curved edges 44 co5perate to clamp the head of the oil plunger 29 in the notch 45. Further, in this connection it will be observed by reference to F ig. 3 that thenotches 45 are so arranged that when the arms forming each yoke are assembled, the same will engage oppositely disposed plungers 29. Accordingly, it will be apparent that upon the yokes 27 being caused to swing, a straight line motion will be imparted to the oil plungers 29.

Referring to Fig. 2 of thedrawings, it

will be noticed that the drain oil outlet is near the bottom of the reservoir 10, which position is selected in order to approxlmately drain the reservoir through the operation of the oil plungers 29, and at the same time collect the heavier than oil particles in the basin 46* from whence they are discharged through the opening 47 upon the removal of the plug 48.

Referring to Figs. 3 and 4 of the drawings it will be observed that the oil plungers 29-difler in diameter, the area of the one designated by the numeral 49 being twice the area of the body 50 of the other, and my reason for thisconstruction will be obvious after the method of operation is fully'explained which is as follows: First, assume that the reservoir 10 is filled withoil in the manner explained above and that the yokes 27 have been given an oscillatory motion throughthe rotation of the shaft 30 and the eccentrics 31 and 32, resulting in'a reciprocating motion of the oil plungers 29. The oil in the reservoir 10 will be drawn through the opening 51 thence through the valves 52, filling the chamber 53 upon the backward motion of the oil plunger 49. Upon the return stroke of the plunger 49 the valves 52 automatically close and the oil in the chamber 53 is forced over the valves into the passageway 54 thence down through the opening 55 to the-oil conduit 56, thence upward through the valve 57, one half of the oil passing out at the outlet 58 to the locomotive cylinder, or any like mechanism to which it may be attached, while the remaining half fills the cavity produced by the retracted plunger 50. Since the plunger 49 has twice the area of the plunger 50 and hence twice the oil displacement it can readily be seen that when the plunger 49 is drawing oil the plunger 50 is forcing oil to the locomotive cylinder, and likewise when the plunger 49 is forcing oil to the cylinders one half of its displacement fills the cylinder occupied by the retracted plunger 50, since both plungers 49 and 50 are operated by one common yoke as clearly shown in Fig. 3 of the drawings. This operation serves to cause a continuous flow of oil to the locomotive cylinders, simultaneous with the oil pump plunger movement. The operation of the other set of oil plungers is the same as that above described hence a continuous flow of oil is furnished in both directions simultaneous with continuous movement of the pump plungers. It will also be noticed in this connection that I avoid the use of additional valves for controlling the direction of the oil by making the displacement of one piston twice the displacement of the other piston.

Without further description and elaboration it is believed that the many advantages of the herein described oil lubricator will be readily apparent.
